principles

Question 1

pauli exculsion principle

Answer 1

states that only a maximum of 2 electrons ,ay be found in a given atomic orbital and if that orbital is filled the electrons will have opposite spin

Question 2

aufbau principle

Answer 2

• states that subshells are filled in order from lowest energy to highest energy
• a lower energy subshell will be completely filled before electrons move into a higher energy subshell

Question 3

Hund’s rule of maximum multiplicity

Answer 3

• electrons in a partially filled subshell will arrange themselves so that to form the maximum number of half-filled orbitals
• every orbital in a subshell being half-filled before any orbital in that subshell is doubly occupied (filled)

Question 4

when atoms lose electrons which electrons would be lost and why

Answer 4

the valence electrons are lost bc they have the highest energy.
